TRY-SQUARE.

$PECIPICA'I'ION forming part of Letters Patent No. 371,878, dated October 18,1887.

Application filed June 25, 1887. Serial No. 242.523. (N model.)

T0 (ZZZ whom, it may concern Be it known that I, J AMES N. Dnnnonon,

a citizen of the United States, residing at Many, in the parish of Sabine and State of Louisiana, haveinventeda new and useful Iniprovemont in TrySquares, of which the following is a specification.

My invention relates to an improvement in try-squares; and it consists in the construction to and arrangement of the parts of the same, which will be more fully hereinafter described, and particularly pointed out in the same.

The object of my invention is to provide a square through the usage of which a perfect 1- joint is obtained and the exact length of the board to be out is given.

A further object of my invention is to pro vide asquare which combines a level and a compass in its construction,thereby rendering the device useful byits embodiment of several tools in one.

l attain these objects by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate similar partsin the several views, and in which- Figure 1 is a perspective view of my improved form of tiysquare. Fig. 2is a similar View showing a spiritlevel and compass embodied in myiniprovenient. Fig. 3shows the manner of applying my improvement in connection with the material to be operated upon, and Fig. 4 is a rear view of the device shown in Fig. 2..

A indicates the head of the square, to one side of which two plates, B B, are secured or formed therewith at right angles. These plates 13 may be provided with scale-marks thereon, indicating inches, as will be readily understood.

0 head A between the ends of the plates B, and through a transverse perforation in the upper end of the head (which communicates with the slot G) is passed the screw-threaded rod or bolt a, having a wing-or thumbnut, a, engag .5 ing with the outer end thereof.. A compassfoot, 0, is mounted at the upper end on the rod a,andit is adapted to be swung out at any desired angle to the head A.

9 represents a groove in the outer side of the head A, which is formed as an extension A slot, G, is formed in the end of the or continuation of the slot G, and the compass foot is adapted toclose into the said groove flush with the rear side of the head. To hold the compass-foot at the desired extension, the wing-nut a is tightened, which draws the sides 5 5 of the head slightly together and binds the upper end of the foot.

Projecting from one end of the head A is a spiked point, a, which forms the center for the compass-leg O, as will be readily understood. On the inner portion of the head A is cut a groove, a", in which groove aspirit1evel, D, is mounted, which is adapted for purposes readily understood in the art.

In the use of my improved device it is to be 6 placed astride of the board to be cut with the under square resting against the piece to be fitted, thus making aperfeetjoint, whether it be at right angles or not, by either raising or lowering the handle. It can also be used as an ordinary try-square, having two parallel blades. The advantage of this construction is in the operation in connection with weatherboarding, flooring, and ceiling or for use where a perfect joint is required. The ap- 75 plication of the bevel-square, compass, and spirit-level are easily understood.

The novelty and utility of my improved de" vice being obviously apparent and appreciable, it is unnecessary to further enlarge upon the same herein.

What I claim as new is-- 1. The square comprising the head A, hav ing the slot G in the upper end, and the blades B B,secured to the head, the spike-point a on 8 5 the lower end of the head, the compass-leg O, pivoted at the upper end in the slot G, and means, substantially as described, for tightening the said leg inits adjusted position, substantially as represented. 90

2. Thesquare comprising the head A, having a groove in its outer side, and the blades 13 B, secured to the upper end, the compassfoot O,pivoted to the head and adapted to close into the said groove,and the spirit-level l) on the inside of the head, as specified.

3. The square comprising the head A, having the slot G in the upper end and the groove 9' on the outer side thereof,and the blades 13 B, secured to the upper end of the head, the

spike-point a 011 the lower end of the head, bolt or rod a, secured in the end of the head across the slot G, thumb-nut a on the end my own I have hereto aflixed my signature in presence of two witnesses.

thereof, and the compass-foot O mounted on JAMES DRAUGHON 5 the said bolt and adapted to close into the Witnesses:

groove 9, substantially as specified. Mr. B. STILLE,

In testimony that I claim the foregoing as JOSEPH D. STILLE, J r.
